APPARATUS FOR MAKING ROOFING FABRIC.

SPECIFICATION forming part of Letters Patent No. 455,000, dated June 30, 1891.

Application filed May 24;, 1890.

To all whom it may concerni- Be it known that I, MINOR O. KERIBAUGH, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Making Roofing Fabrics, of which the following is a specification.

My invention relates to an apparatus or machine for making one or more ply roofing fabrics. v

The principal object of the invention is to provide bearings or journal-boxes for the guide-rollers of apparatus for making roofing fabrics, and more especially two ,or more ply roofing fabrics with certain adjustable features, whereby uniformity in coating, firmness of the union of the sheets of the fabric, and the prevention of any oozing of the coating material at the edges of the sheets is attained in a marked degree.

The invention consists in providing bearings or journal-boxes susceptible of adjustment vertically and adapted for the reception of the guide-roll, which directs and guides the uncoated material to the vat and coating-roll, and in means for clamping said bearings or journal-boxes to place.

The invention furtherconsists in providing bearings or journal-boxes susceptible of a range of adjustment horizontally and adapted for the reception of the guide-roll which directs and guides the coated material from the vat, and in means for clamping or otherwise retaining said bearings or journal-boxes in place.

The invention further consists in making the journals of the guide-roller between the fabric-roll and coating-roll adjustable vertically, and the journals of the guide-roll receiving the fabric between the coating-roll and the second fabric-roll adjustable horizontally.

The invention further consists in the combination and arrangement of an apparatus for making roofing fabrics, as hereinafter described, and particularly pointed out in the claims.

The nature and characteristic features'of the invention will be more fully understood Serial No. 362,973. (No model.)

from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a transverse central section of a machine for making a two-ply roofing fabric embodying my invention and showing guiderolls mounted in journal boxes or bearings susceptible of a range of horizontal and vertical movement and the means for clamping or otherwise securing said journal boxes or bearings to place, also showing the positivelydriven pressure-rolls. Fig. 2 is atop or plan view of the same, showing gear-wheels and a hand-crank for actuating the pressure-rolls. Fig. 3 is a detail View of a guide-roll supported in a vertically-slotted bearing or journal box, showing set-screws attached to the frame of the machine and engaging in said slots. Fig. i is a similar view of a guide-roll mo'unted in bearings or journal-boxes adapted to slide horizontally in ways attached to the frame of the machine and showing screws for shifting and properly retaining said journal boxes or bearings; and Fig. 5 is a similar view of the positively-driven pressure-rolls, showing a screw provided with a hand-wheel for shifting the bearings or journal-boxes of one of said rolls.

Referring to the drawingsfora further description of my invention, a is a brick or other suitable form of furnace, provided with a grate a in the lower part thereof and With a chamber a located above said grate. In this chamber a is mounted a heating-tank b, adapted to contain pitch, tar, or other material. f i

d is a rectangular-shaped main frame supported by the side walls of the furnace aand by twoor more vertical supports d. The upper surface of the frame cl is provided with a spool-bobbin f, adapted to contain a sheet of felt or paper 1, and having a central metallic rod f, surrounded by a rectangular casing or distance piece f and having circular end pieces f attached'to the metallic rod f by means of set-screws or in any other convenient'manner. Of course an ordinary cylindrical roll may be employed for such 'pur pose; but preference is given to. the abovedescribed spool f, because it permits the roll of felt to be easily and quickly mounted thereon and also prevents the felt or paper from accidentally falling off the bobbin.

g is a vat suspended from the frame d into the tank b, and adapted to permit of heated tar or pitch being introduced therein. Above the vat g and journaled to said frame (1 is a plain-surfaced roller h, one portion of which extends partially into said vat.

'i is a spool, bobbin, or flanged roller, similar in all respects to the spool, bobbin, or flanged roller f, but supported in suitable 3' ournals attached to the frame d upon the opposite side of the roller h and adapted to contain a roll of felt or paper 2.

j are bearings or journal-boxes provided with vertical slots 7" and attached to the respective sides of the frame (1 between the spool f and roller h by means of set-screwsfi, so that said bearings may be elevated or depressed, as required, and finally secured to place.

7a is a guide-roller pivotally supported in said vertically-adj ustable bearingsj, for a purpose to be hereinafter described.

1 are ways attached to the upper surface of the frame (Z and located between the roller h and spool i.

'n are journal-boxes permitted to slide on or traverse the ways Z and adapted for the re ception of the guide-roller 0.

p are hand screws suitably attached to the journal-boxes n and engaging in screw-eyes 19, attached to the ways Z, so that thejour nal-boxes 72, together with the guide-roller 0, may be shifted by rotating the screws 1) either toward or away from the roller h, for a purpose to be presently described. Moreover, the friction of the screws p in the screw-eyes p prevents any accidental shifting of the boxes a after the latter have been adjusted.

r is a pressure-roll journaled to the upper surface of the frame (Z by means of a shaft 7', provided with a gear-wheel r and with a hand-crank r sis a pillow-block attached to the under side of the frame (I and providedwith journalboxes s, susceptible of being shifted in vertical slots 5 t is a pressurer01l contacting with the roll a" and mounted upon a shaft 25, supported in the journal-boxes s and provided with a gearwheel 29*, meshing with the gear-wheel T u are screws provided with hand-wheels a, and adapted to shift the journal-boxes s, so as to increase or diminish the contact-pressure between the pressure-rolls r andIt, as required.

The mode of making a two-ply roofing fabric in the apparatus above described may be explained as follows: A fire is started on the grate a of the furnace a, whereby the tar or pitch contained in the tank I) is heated or melted. The vat g, suspended from the frame cl, is then filled with hot tar or pitch, so that the coating-roller h is partially immersed therein. The felt or paper 1, wound around the spool or bobbin f, is passed under the guide-roller 7c, thence over the coating-roller h, partially immersed in the vat and under the guide-roller 0, whereupon'the sheet coated on the underside thereof is united by contact with the end of an uncoated sheet of felt or paper 2, wound around the roller i. The two partially-united sheets are then caused to pass between the pressure-rolls r andt in order to thoroughly unite them. The finished product is then led off from the pressurerolls and laid up for use.

In the practice of the invention the attendant in charge turns the hand-crank 0- which causes the pressure-roll r to revolve, and the rotary motion of the latter is transmitted by means of the gear-wl1eels r and t to the roller 15, so that the two pressure-rolls 'r and t are caused to revolve with the same tangential ye1ocity,thus drawing the two sheets of felt or paper through the machine in the manner above described. Of course the pressure exerted upon the fabric by the pressure-rolls 1 and 25 may be increased, diminished, or otherwise adjusted by turning the screws to, by means of the hand-Wheels it, either in one direction or the other, as required. It may be remarked that during the above operation and by the adjustment of each of the guiderolls 7c and 0 the area of contact of the fabric with the coating-roller 71. may be varied, and thus the attendant in chargeis enabled to regulate to a nicety the amount of coating ma terial applied to the fabric, and by the horizontal adjustment of the guide-roll 0 he can likewise vary the area of contact and the degree of pressure of the coated and uncoated sheets of fabric, and by difierentiating these two, contact and pressure, secures both the requisite amount of coating material and the proper spreading of the same. In other words, by these adjustments the following benefits are secured: uniformity in coating, firmness in the union of the sheets comprising the fabric, and the prevention of any oozing of the coating material at the edges of the sheets.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is.

t 1. In a machine for making roofing fablies, the combination, with a vat containing a liquid or fluid, of a coating-roll partially immersed therein, adjustable journal-boxes arranged on opposite sides of said coatingroll and outside of said vat, tension and guide rolls pivotally supported in said journalboxes, and separate means for shifting said journal-boxes so as to regulate the degree of saturation of the finished fabric, substantially as shown and described 2.
